The two-dimensional DG-SWEM model can be applied to coastal and estuarine systems to solve for time-dependent hydrodynamic circulation and salinity transport. The DG-SWEM model uses the ADCIRC framework (Luettich and others, 1992) and requires inputs of an unstructured finite element mesh. For this study, the mesh domain has an open ocean boundary in the Gulf of Mexico and has higher spatial resolution elements (20 - 100 meters (m)) along the Mississippi and Alabama coast. The model mesh coordinates (latitude and longitude) and simulated average salinity concentrations are included in this data release. For further information regarding model input generation and visualization of model output, refer to Passeri and others (2023). Purpose: These data were generated to examine the effects of interior headland restoration on astronomic tides and salinity transport in Grand Bay, AL. Salinity_GBI_frontal_SLR.zip is a dataset consisting of Federal Geographic Data Committee (FGDC) metadata and a Network Common Data Form (NetCDF) file containing the following variables: coordinates of the model mesh (longitude and latitude) and the average salinity concentration, on the practical salinity scale (pss), for the Grand Batture Island (GBI) restoration frontal season scenario with sea level rise (SLR).
